Mapbox have produced a map of over six billion tweets collected over the last few years. Each geolocated tweet is represented by a green dot. The below map is fully zoomable and interactive.

What makes this map different from other twitter maps is the sheer size of the dataset used - 6,341,973,478 tweets! Time has also been taken to ensure sure the map looks good. Without careful fitlering of the data, unsightly and odd looking banding and splotching would appear on the map.

Working together, EOMAP GmbH & Co KG and MarineFIND, the specialist marine data and service division of FIND Maps, have formed a partnership to offer easy access to coastal high resolution and global bathymetry.

Collecting nearshore zone bathymetry data has, until recently, been an expensive undertaking. However, advances in the processing of satellite imagery means that low-cost, accurate, high resolution bathymetry to a depth of 20m is now available. The EOMAP/MarineFIND partnership has developed a new method for easily distributing this data for preprocessed areas and allows the production of cost-effective custom datasets.

Satellite derived bathymetry from EOMAP and MarineFIND
Dr Thomas Heege, CEO of EOMAP, said: “We’ve worked with MarineFIND on several recent projects and the partnership has delivered excellent results for our clients. Building on the work we’ve already done together, we can now deliver bathymetric and other marine data to many more clients worldwide.”

Nigel West, Consultant at ABPmer, said: “We’re very happy with the satellite derived bathymetry from EOMAP/MarineFIND. It has proved invaluable for the characterisation of shallow coastal areas in the Red Sea and Mediterranean Sea. In our areas of interest, satellite imagery showed shallow bathymetric features that were either inaccessible to survey vessels or beyond the remit of the original surveys. The data we received from MarineFIND showed good validation with our echo-sounder collected data.”

EOMAP is the leading commercial supplier of satellite-derived data for the marine environment. Core services include very high and medium resolution bathymetric surveys, as well as near real-time water quality monitoring. EOMAP holds a unique shallow water bathymetry database that is now available through MarineFIND. Other new products include:

Water quality

Water depth

Seafloor/benthic mapping

Subsurface reflectance

Since 2006, EOMAP has provided marine services to clients in the O&G, coastal engineering and environmental sectors. Applications of their large scale techniques include mapping benthic habitats and bathymetry for the Environmental Agency of Abu Dhabi and mapping the whole of the Great Barrier Reef. Recently, EOMAP launched a WaterQuality App to provide easy access to demo data for Australia (http://eoapp-au.eomap.com/). The aim of their latest partnership with MarineFIND is to extend the provision of easy access to usable, complex data.
